1. If you owe someone money, always pay them back in a bar. Preferably during happy hour.

2. Always toast before doing a shot.

3. Whoever buys the shot gets the first chance to offer a toast.

4. Change your toast at least once a month.

5. Buying someone a drink is five times better than a handshake.

6. Buying a strange woman a drink is still cool. Buying all her drinks is dumb.

7. Never borrow more than one cigarette from the same person in one night.

8. When the bartender is slammed, resist the powerful urge to order a slightly-dirty, very-dry, in-and-out, super-chilled half-and-half martini with a lemon twist. Limit orders to beer, straight shots and two-part cocktails.

13. If he makes it too weak, order a double next time. He'll get the message.

14. If you offer to buy a woman a drink and she refuses, she does not like you.

16. If she buys you a drink, she likes you.

17. If someone offers to buy you a drink, do not upgrade your liquor preference.

18. Always have a corkscrew in your house.

19. If you don't have a corkscrew, push the cork down into the bottle with a pen.

20. Drink one girly drink in public and you will forever be known as the guy who drinks girly drinks.

21. Our parents were better drinkers than we are.

22. Never talk to someone in the restroom unless you're doing the same thing—urinating, waiting in line or washing your hands.

23. Girls hang out, apply make-up, and have long talks in the bathroom. Men do not.

24. After your sixth drink, do not look at yourself in the mirror. It will shake your confidence.

25. It is only permissible to shout 'woo-hoo!' if you are doing a shot with four or more people.

26. If there is a d.j., you can request a song only once per night. If he doesn't play it within half an hour, do not approach him again. If he does play it, do not approach him again.

27. Learn how to make a rose out of a bar napkin. You'll be surprised how well it works.

28. If you can't afford to tip, you can't afford to drink in a bar. Go to the liquor store.

33. The only thing that tastes better than free liquor is stolen liquor.

34. If you bring Old Milwaukee to a party, you must drink at least two cans before you start drinking the imported beer in the fridge.

37. Try one new drink each week.

38. If you are the bar's sole customer, you are obliged to make small talk with the bartender until he stops acknowledging you. Then you're off the hook. The same goes for him.

39. Never tip with coins that have touched you. If your change is $1.50, you can tell the barmaid to keep the change, but once she has handed it to you, you cannot give it back. To a bartender or cocktail waitress, small change has no value.

40. If you have ever told a bartender, “Hey, it all spends the same,” then you are a cheap ass.

41. Anyone on stage or behind a bar is fifty percent better looking.
